Macro Question

[Niwashi]

Neither is currently possible.

Some people use macros that are intended to fail certain steps. For instance, cast something on my target if it's a suitable target, or if that doesn't work, then on my target's target instead, etc. If the first line fails (unsuitable target for the action), then it goes on to the second. If the first works, then the second will fail (because you're busy with the first action). So you get one or the other. Some macros string several of these together, intending that it will always fail on all but one of them, just a different one depending on the circumstances.

Adding the queuing would be complicated, because if one command isn't immediately available, it would have to try to reason out whether it's supposed to skip over that step and move on (as is sometimes intended) or wait for the command to become available. SE could have worked around that difficulty, perhaps making it a separate command (/queueaction or /qac rather than /action or /ac) but they didn't.

I suspect the reason has to do with their desire to prevent macros from being efficient. It's also the reason they disabled fractional seconds in the /wait command. (In beta it allowed tenths of a second, but was changed to whole seconds only.) They were concerned that if macros could be used to achieve as efficient of gameplay as direct actions, they would give too much of an advantage, and become de facto required for hard content. To prevent that, SE deliberately nerfed macro effectiveness, adding extra delays into the /wait command and (I suspect) leaving out the ability to queue actions. (Well, I know they did leave out the ability to queue actions in a macro. What I suspect is the part about this being the reason.)
